SQL Server error on update command - “A severe error occurred on the current command”

Question

Running the following query in SQL Server Management Studio gives the error below.

update table_name set is_active = 0 where id  = 3

Answer 1

In my case, I was using System.Threading.CancellationTokenSource to cancel a SqlCommand but not handling the exception with catch (SqlException) { }

Answer 2

In my case,I was using SubQuery and had a same problem. I realized that the problem is from memory leakage.

Restarting MSSQL service cause to flush tempDb resource and free huge amount of memory. so this was solve the problem.

Answer 3

I just had the same error, and it was down to a corrupted index. Re-indexing the table fixed the problem.

Answer 4

A different scenario but the same error: I got this error when I was trying to insert records into a temporary table using a stored procedure. It turned out there was a parameter mismatch. I was trying to insert a BIGINT into an INT.

Answer 5

There are 3 possibilities on the MS KB

• 959028
• 910416
• 938102

When I see stuff like this: I always think hotfix, engine, server errors etc.

4 results: search for ""Msg 0, Level 11,State 0, Line 0" A severe error occurred on the current command"

Edit: It's on MS Connect too

Answer 6

Run DBCC CHECKTABLE('table_name');

Check the LOG folder where the isntance is installed (\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG usually) for any file named 'SQLDUMP*'
